VALVE.

SPECIFICATIOlXforming part of Letters Patent No. 459,271, clated September 8, 1891. Application filed May 19, 1891. Serial No. [393,310. (No model.)

To (LZZ whom, it may conccrn:

Be it known that 1, J ACOB DREISRNER, of the city of St. Louis, in the State of Missouri, have invented a certain new and useful Iniprovement in Duplex-Port Spring-Puppet Eccentric Valves for Heaters, etc., of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.

This invention is an improvement on my dupleX-eecentric Valve, for which I nade application for a patent filed January 17, 1891, Serial No. 379,(388, to issue May 26,1891; and it relates to a duplex-spring-puppet eccentrio valve both for heatcrs and other uses that has an eecentric Valve stationary plug or stock, with dupleX ports in said plug that tap its tube center on each side of a cut-cit partiton in said tube, and a spring-puppet eceentrie in the case that elastically packs the valve at closed port.

The invention consists in features of novelty hereinafter fully described, and pointed out in the clains. 4

Figure I is a side View of my valve-case with the stock inclosed therein, and shows the screW-fastened cap that covers the springpuppet eccentric. Fig. II is a vertical section taken on line II II, FigzIIl, and shows the spring-puppet eccentric closing that one of the duplex ports that passes through the eecentric of the plug( It also shows the other dupleX port, by which the hot water or steam has free passage to or from the ValVe-chamber. Fig. III is an end View of the plug or stock head, and shows the spring-puppet eceentrie case that surmounts the valve-ease. Fig. IV is a Vertical section taken on line IV IV, Fig. I, and shows the port closed by the spring-puppet eccentric; and Fig. V is a like View with open port.

Referring to the drawings, 1 represents the tubular valVe-case; 9, the combined buffer and spring-pnppet tower that surmounts said case; 3, the screw-perforated integral tableplate at. top of said tower; -ic, the gasket With perforations that register with those of the table-plate, and 5 the perforate cap-plate, whose perforations register With those of the gasket and table-plate, and which cap-plate with said gasket effects a stean-tight joint 011 said table-plate when eompressed home to its seat by the en gagement of the set-screws G in said perfcrations and perforate screwseats in the table-plate. The said set-screws are provided preferably with six-sided heads 7 for seating the wreneh or key that screws then home; but said heads may be made square or with any other number of sides convenient for seating the wrench or key by which they are turned.

8 represents the stationary tubular valve plug or stock, which is connected by steamtight screw-joints 9 to the joint-pipes 10 of the hot-water or other system. The said plug has a clean bore 11, except at the line of denarkation between its respective duplex ports 12 and 12 where a cut-off partition 13 super- Venes.

14: represcnts a projecting eccentrie portion on the valve plug or stock, through which eceentrie passes one of the duplex ValVe-ports 12. The case l slides longitudinallyon said plug until its beveled forward end 15 engages in the eircular beVel-recess 16 in the head 17 of the plug 8, in which circular recess the said bevel end of the case has a free rotary movement to the limit to which it is eonfined by its buffer-pins 18, that are seated in the lugs 10 in said head, and project over said case, and which as the case rotates come, respectively, in contact with one side or the other of the combined butter and spring-pnppet tower 2 at the points respectively of closed port, as shown in Figs. II and IV, and open port, as shown in Fig. V. The said bevel end of the case and its tube-seat 20, which closely fits the swell-saddle eollar 91 next the head of the plug, effects a steamtight joint, while at the same time it does not prevent the partial rotation of said case, as stated, to the limit of the butter-stay.

22 represents the screw-collar that engages with a steam-tight joint on its screw-seat 93 on the swell 21- of said plug', and 95 is the bevel point of said collar, which with its swell-head 26 has a steam-tight seat in the bevel-ended recess 27 in the rear end of the case. The said collar has a six-sided (more or less) wrench-seat 28 for tightening up the union joints of the casing and the plug'.

29 represents a spline set-screw that is seated in the perforate screw 30 in the wrench- IOO seat of the coliar 22, and the projecting point of which screw when screwed home engages in the peripheral spline-groove 31 around the swell 24 of the plug. It will also be seen that as there is a slight latitude in the width of said spline-groove over the thickness of the set-screw after the said collar has been adjusted on its screw-seat to take up the wear, or to either tighten or loosen the joint, the set-screw will still work in the splinegroove to set the adjustment, and will thus prevent the collar from turning loose on its screw-seat.

32 represents an elastic eccentric puppet- Valve that works in the spring-puppet Valvechamber 33 within the spring-puppet tower 2. The arc face 34 of said puppet is seated with elastic pressure on the are face 35 of the projected eccentric portion 14 of the plug under the influence of the spiral spring 36 that is housed in the socket-boxing 37 in said eccentric puppet, and whose upper end pushes against the cap-plate 5 that surmounts said tower.

38 represents a pendent lug that projects from the bottom of the case 1, and which lug is provided with a perforate lever-seat 39, in which any suitable lever or handle may be inserted and fastened to its seat by the setscrew 40 for turning the case 1. Now it will be seen that the arc face 34 of the elastic puppet eccentric valve 32 always keeps its elastic seat on the arc face of the eccentric portion 85, and when the case is turned round to its closed position, as shown in Fig. IV, and to its butter limit on tha-t hand, the tower 2, having been arrested by coming in contact with the buffer-pin 18 on that side of the stationary plug, the arc face of the spring-puppet then covers and closes the member 12 of the duplex ports of said plug, and the hot water or other fluid that passes through said valve system is arrested in its passage. When again it is required to open the port and renew the passage of the hot water, the., the case, with its eccentric puppet-valve, is turned round into the position shown in Fig. V, with the tower buffed against the other butter-pin, when the member 12 of said duplex ports is opened and a free current ensues.

I have shown the plug stationary and the case movable, as it is most convenient to have said plug stationary in consequence of its connection with stationary supply and discharge tubes and the case is the more easily made adjustable; but I do not confine myself to said respective actions of said parts, for it is evident that the case may be made stationary and the plug adjustable without departing from the essential features -of the inventor. The movement, it will be seen, is very slight to effect, respectively, the opening and closing of the dupleX ports, the unclosing of the port 12 providing` a free course for the flow both through said port and through the port 12% It is also evident that when the flow is required to be only restricted, and not stopped to limit the flow of water, the case can be partly turned, stopping short of its bufier limit, and so regulate the Volume of the flow.

The combination of the tubular Valveplug S, having an eccentric portion 14 on one part of its periphery, said plug being provided with duplex ports 12 12,and having a cut-off portion 13 between said ports, the tube-case 1,that houses said valve-plug, and the elastc eccentric puppet-valve 32, that works n said tube-case, substautially as and for the purpose set forth. 2.
